Solve the equation. \[ \frac{x-18}{x-9}=-\frac{9}{x-9}+8 \]

3) \( \begin{array}{l}2 x+y=1 \\ 2 x-y=3\end{array} \)

Form a polynomial whose real zeros and degree are given. Zeros:-5,-4,3,5; degree: 4 . A polynomial with integer coefficients and a leading coefficient of 1 is \( f(x)= \). (Simplify your answer.)

\( 36 x ^ { 3 } - 13 x + 5 \rightarrow a x ^ { 2 } + b x + c \)

6. \( f(x)=\left(x^{2}-1\right)\left(3 x^{2}-6 x+5\right)-(x+4)\left(4 x^{2}-2 x+1\right) \) 7. \( f(x)=\frac{3}{2}(\sqrt{x}-4)(4 x-5) \) 8. \( f(x)=(2 x-1)(3 x+4)(x+7) \) 9. \( f(x)=\frac{8 x^{2}-2 x+1}{x^{2}-5 x} \) 10. \( f(x)=\frac{x^{2}-4 x+3}{2 x^{2}-3 x+2} \)

1. Find the product of \( \left(\frac{x}{4}-\frac{1}{3}\right) \) and \( \left(\frac{x}{4}+\frac{1}{3}\right) \) (Algebraic fructions)
